I know the area well! Liberal Californicationists are ruining Montana in every previously down to earth town or city they inhabit. Some of the smaller more Eastern Montana cities absolutely HATE Californians because of their ideas and how they are making the land and housing skyrocket in value, making places unaffordable for locals.
Since you are a Bitterroot valley man, You must know where my paternal roots began in the USA. One relative grew up on the Burnt Fork, and my great grandfather's tiny log home is now part of the Stevensville Park and museum. I think they may have painted it white, when I saw it about 20 years ago. I lived near Craig, Montana on the river for 12 years. They filmed part of "The Untouchables" on the Hardy bride about 1 1/2 miles from my house, as well as "Thunderbolt and Lightfoot" when Lightfoot was riding in the Cadillac with Clint in the final scene. My favorite part of Montana!
BTW, That cabin was real, and the owner ended up tearing it down completely because idiots constantly trespassed to get to it after the movie, and would go in it, steal items and take parts of it home as movie memorabilia. ASSHOLES! It was a cool part of the area. Probably LIBERAL tourists **** with it.
